Sorry but only because you read certain books it not makes you automatically a winner. You might missunderstood some of the concepts you read about.
If you play your hands correctly you will for sure not always lose with premiums. Not on stars, not on other pokersites and not in live poker. A lot of advanced beginners think the game is rigged because they lose but they simply make tons of mistakes and/or not put in enough volume.
What's up with that? Wish I could tag the @pokerstars rep
